Phone Network

configure the local area network to accommodate a number of network designs, which varies by
organization and Yealink IP phones.

IPv4 and IPv6 Network Settings
Yealink IP Phones support IPv4 addressing mode, IPv6 addressing mode, as well as an IPv4&IPv6
dual-stack addressing mode.
After connected to the wired network, the phones can obtain the IPv4 or IPv6 network settings from a
Dynamic Host Configuration Protocol (DHCP) server if your network supports it. To make it easier to
manage IP settings, we recommend using automated DHCP which is possible to eliminate repetitive
manually data entry.
You can also configure IPv4 or IPv6 network settings manually.
Note
Yealink IP phones comply with the DHCPv4 specifications documented in RFC 2131, and DHCPv6
specifications documented in RFC 3315.
